Quality Control

Our (βr,4As,8Ar)-1,4,4A,5,6,7,8,8A-Octahydro-β,4A-Dimethyl-8-Methylene-2-Naphthaleneethanol is produced and tested under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC/GC for purity and identity confirmation, to ensure it meets precise customer specifications and internal standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
